SPECIFICATION forming part of Letters Patent No. 426,116, dated April 22, 1890.

Application filed May 13. 1889- Serial No. 310,616. (No model.)

To all whom it may concern: In the said drawings, the reference-numeral Be it known that I, \VALTER J.

The construction :00

and arrangement of these pansneed not differ essentially from those in the ordinary form of sweeper.

The sweeper is propelled by a handle 25, attached to the casin g in any desired manner.

I11 using the apparatus it is intended that the direction of motion shallbe such that the brush-rollers, whiclralways turn in opposite directions, shall have their lower portions which are in contact with the floor or carpet moving toward each other. In this manner the rubbish upon the .fioor is picked up between the bristles of the contiguous or adjacent brushes, carried up between them, and then over into the pans, instead of being swept directly into the pans, as usual. By this operation large and more than ordinarily heavy substances are taken up with ease, whereas the sweepers heretofore used would be unable to accomplish such a result or would effect it imperfectly.

It is evident that the mechanism for driving the brush-rollers may be very widely varied, as also may be the devices wherein the rollers are journaled. I donot, therefore,

limit myself to any special form of such de vices, my invention consisting, broadly, in the employment of two oppositely-revolving contiguous brushes, and in means for giving a simultaneous vertical adjustment thereto. 0

Vhat I claim is.

1. I11 a carpet-sweeper, the combination, with a casing, of two brushes supported in such juxtaposition that they co-operate to pick up and carry particles, and mechanism 35 for revolving the brushes so that their lower portions move toward each other, substantially as described.

2. Ina carpet-sweeper, the combination, with a casing and two brushes arranged in 40 juxtaposition, of pans arranged outside said brushes and mechanism for revolving the brushes so that their lower portions move toward each other, substantially as described.

In testimony whereof I aflix my signature 45 in presence of two witnesses.
